By default, MIUI comes with a lot of system apps that replace stock Android's own apps and also provide popular features that you would usually get from third-party apps from Google Play. Despite what they offer, many users see these apps as bloatware and want to get rid of them to clear up space and have less icons on the home screen. MIUI doesn't give the user the option to remove these apps and services but the Android Debug Bridge is capable of doing that.
